How do you solve, 1/2 - n = 3/8

Question

What is does n equal in this problem?

1/2 - n = 3/8

Answer 1

1/2 - n = 3/8

Subtract 1/2 from both sides of the equation:

-n = 3/8 - (1/2)

Then you need to make the denominator (the number on the bottom of the fractions) the same:

-n = 3/8 - (1/2)x(4/4) = 3/8 - (4/8) = (3 - 4)/8 = -1/8

Now you can divide both sides by negative 1 to get:

n = 1/8
